Term, live abdominal pregnancy secondary to rupture of a uterine rudimentary horn is
a rare condition. Pregnancies conceived in the rudimentary horn of the uterus usually rupture
during early gestation and present as a catastrophic event. However, rarely, after rupture of the
uterine horn the foetus may continue to grow in the abdominal cavity and reach term gestation.
A primigravida with a term pregnancy was referred to our centre for caesarean section with
ultrasonography findings of transverse lie and placenta previa. During surgery, a live baby
was extracted from the abdominal cavity, revealing a bicornuate uterus with rupture of the
rudimentary horn. The early peroperative diagnosis and prompt control of the bleeding with
excision of the rudimentary horn and transfusion of multiple blood products saved the patient’s
life. The case is presented for its rarity and to highlight the importance of a high index of suspicion
in cases presenting with abnormal foetal presentation.
